← HistoryWhich outcome increased the lifespan of geared sakia waterwheels, developed and used in Ancient Egypt, that were constructed with bronze components?
A)Reduced electrochemical oxidation rates✓
B)Increased magnetic eddy-current damping
C)Improved grain crushing performance
D)Greater centrifugal pump efficiencies
💡 Explanation
Electrochemical oxidation caused primarily by water salinity and mineral impurities attacks bronze alloys. Reduced oxidation rates resulted therefore in slower material loss due to passivation forming a protective layer, rather than accelerated corrosion weakening the gears.
